CLEANING DEVICE FDR YARN-MARKETS: MACI'IIIIES.

Application filed May 20,

My invention relates to an improvement in cleaning devices for yarn making machines, drawing frames, twist-in frames, Speeders and other machines of similar character.

At present this cleaning of the thread boards and roller beams is imperfectly ac complished by hand. An operator takes a block of wood having a flannel pad on its underside (very much like a chalk eraser) or a handful of waste and passes, it over the thread boards, poking it along under the yarn, and unless the operator is skillful and cautious he is very apt to break the yarn.

or get bunches on the yarn as he is doing this, thereby requiring him to mend the ends and .so lose time.

My invention has for one of its objects the provision of an automatic reversible means to clean the fly and lint from the thread boards, roller beams and finger boards of yarn making machines and to lessen the slugs and bunches in the finished yarns, thereby improving the quality of the yarn.

Another object of my invention is to relieve the operator from the labor of cleaning these parts of the machine thus enabling him to devote more time to the piecing up of broken ends or to run a greater number of spindles whereby the cost of production is correspondingly reduced.

A further object of the invention is to provide an improved wiper so designed that should any of the brackets holding the thread guides be raised, the wiper nevertheless passes over them, which is done by sliding the brackets back into position.

In the. description, reference will be made to spinning machines but it is to be understood that this is only for the purpose of illustration and not limitation. The cleaning device may be arranged to clean only one side of a frame or it may be constructed to clean both sides as will appear from the descriptionwhich follows, taken in connection with the drawing.

A still further object of my invention is to provide a reversing mechanism operative by the front and rear wipers to change the direction of n'ovement so that the front wiper is always in front and the rear wiper remains at all times in the rear.

Referring to the drawings:

Fig. 11 is a plan view of the rear wiper.

Fi 12 is a perspective view of the hold o l I mg bracket for the reverslble mechanism.

' Similar numerals refer to similar parts throughout the several views.

In the drawings, see Fig. 2, A and B designate the end frames, C the top board, 1) the roller beams, E the thread board, F the linger boards or yarn guide brackets, G the roller stands and H rovings in the creels, and J, one of the weight lever mechanisms.

The cleaning mechanism comprises a reversing mechanism L at one end of the spin ning machine, two front wipers I located on the outersi-des of the spinning machine, two companion rear-wipers K which clean parts not reached by the front wipers, two Y-shaped brackets N at the other end of the spinning frame, and brackets having arms of unequal length for a purpose to be hereinafter stated, and a split sheave oppositely situated to the reversing mechanism but located at the same end of-the machine. A wire or cord P to which is secured the wipermeans passes around the several grooved pulleys or sheaves. This arrangement renders possible the cleaning of both sides of the spinning machine while using only one reversing mechanism.

The front wiper cleans the thread boards, front half of roller beam, the yarn guide The front wiper is another distinctve feature of my invention. As shown in Fig. 9 the front wiper is of the clam shell type, its top part 44. being stamped out of a blank as then shown. The rear of the top part is turned down to form a flange 4L5 andthe corners slit and looped to receive the angle ends 47 of the wire bottom member 48 in hinged relation as shown in Fig. 10. The front part is curved downwardly to make it flush with the thread guides. Secured by bolts to the inner face of the flange are two strips of wood 49 or other suit-able material on each side leaving a clearance for the insertion and operation of the ratchet or takeup key 50. The sides of the top part which face the ends of the frame are curved to form plows 51, 51 for lowering the yarn guide brackets when the latter are in lifted position. A portion of the top metal part is stamped inwardly as shown at 52 which with the flange pro-' vide bearings for the ratchet key 50. Holes 53, 53 are provided in the shank of the key for receiving the ends of the wire or cord strand P. A pawl 54 is stamped out of the metal top for securing the key against relative movement.

To tighten the wire or cord it is only necessary to turn the key by its rectangular end 55, the pawl acting as a brake to prevent slipping back. Other means of tensioning the wire may be used without departing from the spirit of my invention. As before stated, there is hinged to the rear flange of the wiper a U-shaped wire base 48 upon which a flannel cleaning band 56 or similar material may be slipped. This fa ilitates removal and replacement of the flannel band. The curved ends of the top partof the front wiper act as plows and are so designed that in the event that the yarn guide brackets are raised during the ope "ation of the cleaner there is no interference with the travel of the front wiper as the yarn guide brackets are plowed down by the sliding of the curved ends against the brackets. This action takes place in either direction as both of the ends have a similar plow curvature. The size of the top metal part of the front wiper is such that it completely covers the thread board and extends outwardly to the ends of the yarn guide brackets. The front wiper is rearwardly equipped with long brushes 57 such as shown in the drawing which serve to clean the parts of the machine not reached by the rear wiper. These brushes are attached to the wooden strips, this fastening means affording an easy way of removing the brushes.

The rear wiper is simple in structure and comprises a block of wood 58 having on its underside a flannel pad. Projecting out rom the front, rear and top of the block are long brushes 60 similar to the brushes on the front wiper, which clean a large areaof the machine surface particularly the portions of the area which are diflicultly accessible to the operator such as the weight levers and lover screws.

Although cord may be used, I have found that piano wire gives the best results. Because of the working strain imposed on a cord or wire, it is important to use a strand of strong and resistant material, and I have found after long experimentation that this desideratum is best served by piano wire.

The arrangement of the cleaning device is as follows: The reversing mechanism L is mounted at one end of the machine. Next the double sheave brackets N are mounted at the other end on both sides, while the split sheave O is mounted on a stanchion which is cut away for that purpose, and is disposed oppositely to the reversing machine at the same end. It is to be noted that the distance between the outer periphery of the inner sheave and the outer periphery of the outer sheave of the bracket is equal to the diameter of the large sheave in the reversing mechanism and the split sheave O. The wire or cord (but preferably piano wire) is passed around the sheaves after the manner shown in Fig. 2 and the endsare brought together within one of the front wipers and are secured to a ratchet key which through a pawl arrangement renders it possible to tighten the wire or cord in case of stretch or sagging. Of course other means of tightening the wire may be employed such as would be possible if the brackets N were made adjustable outwardly but I find that my proposed means gives satisfactory results. Before attachingthe rear wipers, the front wiper to which'the ends of the piano wire are secured for adjustment should be brought to the extreme position where it contacts the reversing mechanism. The front wiper on the other side is attached to the wire at a point closely adjacent the outer sheaves of the bracket. The rear wipers are attached to the wire by means of screws and they are placed at points exactly opposite the front wiper, that isthe rear wiper on the side with the reversing mechanism is attached at a pointnear the inner sheave of the bracket and the other rear wiper is attached at a point adjacent the split sheave. In other words the first front wiper and the second rear wiper are in staggered relation to the first rear wiper and the second front wiper. The wire passing around the sheaves should present three sections ofparallelly disposed strands of wire.

As before stated, if it is desired to operate only one side of the spinning machine, the Y-shaped brackets are dispensed with and the split-sheave O employed. So that on each side there would be a reversing mechanism and a splitsheave around which the wire would travel. In place of the OCI A device adapted to be used for removing a Wheel from an axle upon Which it is keyed comprising a body provided at its opposite ends With alined sockets of different sizes, and anvil plugs fitting in the sockets.

In testimony whereof I affix my signature.
